Definitions

  • the present invention relates to an energy-supplementing saccharide source and its uses, more particularly, to an energy-supplementing saccharide source essentially consisting of trehalose prepared by the method containing a step of allowing a non-reducing saccharide-forming enzyme to act on a partial starch hydrolysate exhibiting a reducing power, and to an energy-supplementing composition containing said trehalose as an effective ingredient.
  • Saccharides exhibiting a reducing power, such as glucose and fructose have been used for a long time as an energy-supplementing saccharide source. These saccharides, however, have a relatively-poor storage stability because of their reducing power, and, generally they become more unstable in the coexistence of other nutritives such as amino acids and vitamins.
  • an energy-supplementing saccharide source essentially consisting of a non-reducing saccharide such as xylitol, sorbitol, maltitol, lactitol, sucrose or trehalose has been in great demand.
  • a non-reducing saccharide such as xylitol, sorbitol, maltitol, lactitol, sucrose or trehalose
  • sugar alcohols of monosaccharides such as xylitol and sorbitol have a demerit of that they may cause a serious diarrhea when administered to the body with an erroneous dose and route.
  • Sugar alcohols of disaccharides such as maltitol and lactitol, as disclosed in Japanese Patent Publication Nos.

  • the trehalose prepared by the biochemical technique is an absolutely novel energy-supplementing saccharide source with an extensive applicability because of its non-reducing property, and established an energy-supplementing composition containing said trehalose as an effective ingredient.
  • the energy-supplementing composition according to the present invention can be arbitrary used in combination with other nutritives and/or medicaments, and formed into multiple nutritive compositions and pharmaceutical compositions with an improved therapeutic efficacy because trehalose incorporated therein has a satisfactorily-high storage stability and does not substantially exhibit a reducing power.

  • the product a 30% powdered juice, d.s.b., is stable for a relatively-long period of time without giving an unfavorable taste and smell and causing solidification by absorbing moisture.
  • the product can be arbitrarily used as an energy-supplementing composition.
  • Egg yolks prepared from fresh eggs were sterilized by a plate heater at 60-64°C, and one part by weight of the resultant liquid was mixed with 4 parts by weight of an anhydrous crystalline trehalose prepared by the method in Experiment 1-4.
  • the resultant mixture was placed in a container and allowed to stand overnight to form a block while allowing trehalose to convert into hydrous crystalline trehalose.
  • the block was pulverized by a cutter to obtain a powdered egg yolk.
  • the product can be arbitrarily used as a material for confectioneries such as a premix, ice cream and candy, and emulsifier, as well as an energy-supplementing composition for oral and intubation feedings.
  • a composition consisting of the following compositions was prepared: Five hundred parts by weight of hydrous crystalline trehalose prepared by the method in Experiment 1-2, 270 parts by weight of powdered egg yolk, 209 parts by weight of defatted milk, 4.4 parts by weight of sodium chloride, 1.8 parts by weight of potassium chloride, 4 parts by weight of magnesium sulfate, 0.01 part by weight of thiamine, 0.1 part by weight of sodium ascorbate, 0.6 parts by weight of vitamin E acetate, and 0.04 parts by weight of nicotinamide. Twenty-five g aliquots of the composition were injected into moisture-proof laminated small bags and heat sealed to obtain the desired product.
  • One bag of the product is dissolved in about 150-300ml of water into a fluid food, and orally administered or parenterally administered to nasal cavity, stomach and intestines by intubation feeding as an energy-supplementing composition.
  • a hydrous crystalline trehalose powder prepared by the method in Experiment 1-2, was dissolved in water into an about 10 w/v % aqueous trehalose solution which was then in usual manner membrane filtered to remove pyrogen, aseptically injected into a plastic bottle, and sealed to obtain the desired product.
  • the product a satisfactorily stable hyperalimentation substantially free of change on standing, is suitable for intravenous- and intraperitoneal-administrations.
  • a 10 w/v % solution of the product is isotonic to blood, and this means it supplements energy to living bodies at 2-fold higher concentration than in the case of glucose.
  • a hydrous crystalline trehalose, prepared by the method in Experiment 1-2, and an amino acid composition consisting of the following components were dissolved by stirring in water to give 5 w/v % and 30 w/v %, respectively, and, similarly as in Example 10 the resultant solution was purified into a pyrogen-free solution which was then injected into a plastic bottle and sealed to obtain the desired product.
  • Components of amino acid composition Component mg/100 ml L-Isoleucine 180 L-Leucine 410 L-Lysine monohydrochloride 620 L-Methionine 240 L-Phenyl alanine 290 L-Threonine 180 L-Tryptophane 60 L-Valine 200 L-Arginine hydrochloride 270 L-Histidine monohydrochloride 130 Glycine 340
  • the product is a multiple hyperalimentation of trehalose and amino acids, it is satisfactorily stable without substantial change on standing and can be suitably administered intravenously and intraperitoneally to living bodies.
  • the product can be favorably used as an energy-supplementing composition to supplement energy as well as amino acids.
  • a crystalline trehalose powder prepared by the method in Experiment 1-3, was admixed with 50 parts by weight of methanol solution containing 3 parts by weight of iodine, and the resultant solution was mixed with 200 parts by weight of a 10 w/v % aqueous pullulan solution to obtain a traumatic ointment having a satisfiable extensibility and adhesiveness.
  • the iodine contained in the product exerts a bactericidal activity, and the trehalose in the product acts as an energy-supplementing saccharide source on viable cells, and because of these the product shortens a healing period and satisfactorily heals a wound surface.
  • the resultant tablet was further coated with 65 parts by weight of a fresh preparation of the same hydrous crystalline trehalose, one part by weight of pullulan, and 34 parts by weight of water.
  • the tablet thus obtained was glossed with a wax solution to obtain the desired product with a satisfiable appearance.
  • the product which is readily preparable by the above-mentioned coating step, has a relatively-high shock-tolerance, and retains its high quality for a relatively-long period of time. Thus, it can be suitably used as an energy-supplementing composition.
  • the present energy-supplementing saccharide source essentially consisting of trehalose, prepared by the method containing a step of allowing a non-reducing saccharide-forming enzyme to act on a reducing partial starch hydrolysate, has a satisfiable stability without substantially exhibiting a reducing power, as well as possessing a character of being readily metabolized in vivo and utilized by living bodies as an energy source.
  • the present energy-supplementing composition containing as an effective ingredient trehalose prepared from reducing partial starch hydrolysates by a novel biochemical technique, has a character that it can be readily prepared into more satisfiable multiple nutritive compositions in combination with other nutritives and medicaments, as well as into pharmaceutical compositions with an increased therapeutic efficacy.
